Large-scale fabrication of highly elastic conductors on a broad range of surfaces
摘要： Recently, a great stretchability progress has been witnessed in elastic electronics. However, such electronics are either costly, toxic, or cannot pattern on a broad range of substrates which limit their large-scale fabrications and applications. Here, to overcome those limitations, an ink comprising liquid metal particles and desirable polymer solutions is developed. The polymer solutions in our ink can be adjusted to print on different surfaces and avoid toxic organic solvents in most cases. The ink can be sintered by small strain (~10%) in room temperature. Using our ink, conductors with high stretchability (380,000 S/m at a strain of 1000%) can be printed in low consumption (liquid metal consumption 3.27 mg/cm2), in large area (bestrew entire surface of a T-shirt) and in high throughputs (~105 cm2 per hour). The ink can be printed on a T-shirt to achieve a smart wearable platform that integrates electronics for strain/electrophysiology/electrochemistry detection, and temperature monitoring/controlling.

Non-contact Laser Printing of Ag Nanowire-based Electrode with Photodegradable Polymers
摘要： The roll-to-roll process is synonymous with newspaper production. If a similar high-throughput process is developed to fabricate electronics over large areas, it would revolutionize the printed electronics manufacturing process. Rapid fabrication of electrode, including patterning and nanoscale welding, is a necessary integration technique to reduce the duration of the process, but faces difficulties in being realized using conventional methods. This paper discusses material factors that affect printability, in the context of developing a promising fabrication technique called laser induced forward transfer (LIFT); LIFT is non-contact printing technique applied previously to realize simultaneous pattern deposition and nanowelding of Ag nanowire (AgNW)-based electrodes. A photodegradable polymer, which is a key component in the printing process to render droplet acceleration, is investigated with regards to its mechanical and optical properties. Furthermore, the printing process of the AgNW-based electrode is visualized, resulting in deeper understanding of LIFT. Knowledge of these factors will contribute to rapid and precise patterning of AgNW-based electrodes with high stretchability and transparency toward flexible optoelectronics devices.

Laser Sintering of Zn Microparticles and Its Application in Printable Biodegradable Electronics
摘要： The rapid expansion of electronic technology and short lifespan of consumer devices create a huge amount of electronic waste. The disposal of discarded devices represents a serious environmental challenge. Biodegradable devices are able to decompose into benign components after a period of stable operation during its service life, which represents a potential solution to reduce the environmental footprint of electronic technology. The widespread applications of biodegradable electronics are still hampered by the lack of facile manufacturing approach for high quality devices. Here, a laser sintering technique to weld naturally oxidized Zn microparticles into biodegradable conductors is reported. The sintering process is carried out under ambient conditions and compatible with various biodegradable substrates. A low-cost fabrication procedure involving stencil printing and laser treatment is established to create conductive features with excellent conductivity and mechanical durability. The practical suitability of printed Zn conductor is demonstrated by fabricating near-field communication tags, which are flexible and fully functional with the transient behavior modulated by the choice of packaging materials. The printed biodegradable conductor may find potential applications in eco-friendly sensors, transient printed circuit boards, and implantable medical devices.

Solution-processed inorganic p-channel transistors: Recent advances and perspectives
摘要： For decades, inorganic n-type metal-oxide semiconductors have attracted great interest across a wide range of applications due to their excellent electrical property, low cost, high optical transparency, and good ambient stability. The next attention has focused on the development of high-performance p-type semiconductors with comparable opto/electric properties to n-type counterparts. This paper provides a comprehensive overview of recent progress in solution-processed inorganic p-type semiconductors that can be applied as channel layers in thin-?lm transistors and complementary metal-oxide semiconductor-based integrated circuits. We ?rst introduce conventional p-type oxide semiconductors and review their achievements on related devices. Then, we pay a speci?c focus on emerging (pseudo)halide materials for realization of transparent, low-temperature and high-performance printable electronics and circuits.
